Abstract

PURPOSE:To enable effective switching to a power-saving mode, by providing a time-setting means for variably setting the period of time required for switching to the power-saving mode depending upon a command from an image signal-generating device or by a switch or the like, and freely setting the time for switching to the power-saving mode. CONSTITUTION:An image signal-generating device 2 supplies a printer 1 with a signal indicative of the time (x) for switching to a power-saving mode depending upon a command PAUSE[x], before transmitting an image formation start signal ST. After transmission of the start signal ST, a series of image signals IMG is transmitted, and the printer 1 starts an image-forming operation. When the input of the image signals IMG runs out after a predetermined lapse of time, a waiting condition is provided, and when the waiting time exceeds the time (x) stored in a register 102, a fixing device 12 and the like are set into a non-driving condition with that timing, thereby switching to the power- saving mode. The image signal-generating device 2 sets the time (x) for switching to the power-saving mode, taking into account the image signal- generating period of its own, whereby a most effective power-saving effect can be realized.

Laser printers and LED printers have internal instruments that consume a large amount of power, such as a fixing device and a cooling fan. That is, a laser printer includes a scanner motor for scanning laser light, a fixing device for fixing a developed image, and a cooling fan for cooling heat-generating parts as devices that consume large amounts of power. Similarly, an LED printer has a fixing device for fixing a developed image and a cooling fan for cooling various heat generating parts.

(Problems to be Solved by the Invention) However, in conventional printers that are equipped with means for switching to power saving mode, the switching time to double power mode after image formation is fixed to a certain period of time. However, if the processing speed of an image signal generation device such as a computer that supplies image signals is slow, the printer may enter power saving mode while generating image signals for the next page, causing the printer to In order to form an image for one page, it is necessary to send out a power saving mode release signal before sending out the image signal.Furthermore, after sending out the power saving mode release signal, devices such as the fuser are prepared. It becomes necessary to wait until the transmission of the image signal is completed.

Note that if you lengthen the time it takes to switch to power saving mode,

[Operation] The switching time to the power saving mode is set using a command from the image signal generation device or a switch. Then, the printer side switches to the power saving mode after this setting period has elapsed. Therefore, if the switching time to power saving mode is set by considering the processing speed of the image signal generation device or the time interval of image generation operations, the fuser, etc. will not be turned on and off frequently and will be most effective. It is possible to obtain significant power saving effects and solve problems such as lifespan and noise.
